Plugin Usage: Warning: React version not specified in eslint-plugin-react settings.

[bhardy]

I am getting a similar issue to (#1955, #1857) where I receive the warning ( Warning: React version not specified in eslint-plugin-react settings) when I only add react to my plugins and not my extends. We only want to grab 2 rules from react. I have the settings object in my eslintrc.json with the "settings": { "react": { "version" : "16.3.2" }}, along with rules:

  "rules": {
    "semi": ["error", "always"],
    "eqeqeq": "off",
    "react/jsx-no-bind": "off",
    "react/no-deprecated": "error",
    "no-console": "error"
  }

If I put react (or "plugin:react/recommended" into extends I no longer receive the warning, but I don't want to extend the rules.

Please let me know if this is an issue or if I'm doing something wrong!

Thank you

I'm getting this warning as well, even with plugin:react/recommended in extends. Here's my .eslintrc.json:

{
    "extends": ["eslint:recommended", "plugin:react/recommended"],
    "parser": "babel-eslint",
    "parserOptions": {
        "ecmaVersion": 6,
        "sourceType": "module",
        "ecmaFeatures": {
            "jsx": true
        }
    },
    "plugins": [
        "react"
    ],
    "env": {
        "browser": true,
        "es6": true
    },
    "rules": {
        "no-console": "off"
    }
}

The page this error links to (https://github.com/yannickcr/eslint-plugin-react#configuration) doesn't mention anything about specifying the React version in the eslint config. Should this warning just be removed?

@nikolas it definitely does; it’s listed there under “detect”. Regardless, if it didn’t, we’d need to fix the docs, not remove the warning.

I believe this issue should be fixed now in v7.12.4; closing.

Please file a new issue if it’s not.
